On my apexi SAFC, the knock sensor reading is unreasonably high...even at idel where knock is vurtually impossible it still reads that there is knock, then at higher rpm's the knock goes down then raises agian, the engine makes no noise other then normal engine noise, no knock no nothing...just wondering if anyone has had a similar thing happen with their afc, thanks for the info

 

try running a higher octane, that might reduce your knocking (if there's any). if that doesnt work try retarding your timing. as far as dealing with our apexi safc, ii dont know.
just because you dont hear it doesnt mean it isnt there.
